Brain Stimulation and behavioural cognitive rehabilitation: a new tool for neurorehabilitation? A foreword

This special issue of Neuropsychological Rehabilitation aims to present new knowledge about a recent and innovative approach that can possibly ameliorate the outcome of the rehabilitation of cognitive deficits, namely: non-invasive brain stimulation (NIBS). The issue includes a series of papers on NIBS and combined rehabilitation studies (reviews and some original contributions), highlighting the challenges, as well as the power, of this novel approach. The old and time-honoured concept that the brain structure becomes immutable after childhood has been abandoned, based on the evidence that all areas of the brain remain plastic in adulthood and during physiological ageing, with even some evidence for neurogenesis (Berlucchi, this issue).
